fix(imap): fail fast on LIST errors

Browse Source 
async-imap returns infinite stream of errors
in case of EOF or timeout on the input stream,
so attempting to skip and log errors results in busy loop
similar to this:

To avoid busy loop, fail fast on first error
and bubble it up instead of trying to recover.
